HB TCXX Rear Shock Tower (Let Down) by Arrowmax AM-TCXX-68764-V2  [AM-TCXX-68764-V2]

Rear shock tower overview

This Arrowmax AM-TCXX-68764-V2 rear shock tower is an aftermarket RC-scale replacement part produced for the HB TCXX platform, presented here as a let-down style mount that changes rear shock positioning. Its role is to provide a defined mounting point for rear shocks to alter shock angle and leverage, enabling incremental suspension tuning without modifying other suspension components.

The piece is intended as a direct-fit option for HB TCXX cars, used when adjusting rear roll behaviour, shock compression onset, or when testing different shock angles during chassis setup. Because it affects the geometry of the rear suspension, installers typically compare handling before and after fitment to evaluate changes in traction and roll response.

Installation notes focus on fit and function rather than stepwise instructions: confirm alignment with the HB TCXX shock towers and ball studs, ensure mounting surfaces are clean, and verify that shock travel remains unobstructed after fitting. During setup, use changes to this tower in combination with spring, damper and sway bar adjustments to dial in rear grip and transient response.
